The bombarding rate at which the graph of construction industry is shooting up in Kerala is alarmingly a massive threat on the environment. In the economically rich and middle class world building construction is becoming a non-essential luxury. The God’s own greenery of Kerala is giving way to concrete sky scrapers. The demand for more buildings is only increasing forgetting the fact that the exploitation of our precious resources costs us the earth.
The environmentalists today are fighting a hard but losing battle against the massive exploitation of green fields, ponds, hills, woods, metal, sand and stone that is being constantly sacrificed on the alter of construction boom. The craving for burgeoning building culture is becoming uncontrollable. The growing exploitation of natural resources threatens our very existence. The environmentally unsound luxury of cement, bricks and steel gives a dead look to houses where the solid walls won’t breath and the need foe breaking the walls to get a whiff of fresh air arises. It is high time we are anxious about the way we design our houses, flats, offices etc. Is it not possible to put a full stop to the so called blueprints that serve as a top polluter of the country’s natural resources?
The concept of eco-friendly begins with our understanding of its relation with space allocation. How much of space do we use up to make our homes, how many resources do we exploit and how much energy is consumed all led up to this answer. Like Gandhiji said: “The earth has enough to satisfy every man’s need but not his greed”. Therefore a green home is defined as one that uses less natural resources, water and energy and thereby reducing environmental impacts and a green home is an environmentally sensitive home.
A building should be a biotic form. It should breathe life and exhale energy to the inmates who move around under the roof. It can be achieved only through sustainable construction solutions where a house becomes an inevitable part of nature and the people feel the splurge of nature both inside and outside. This intellectual pursuit takes us to the fusion of aesthetic sense, economic sense and common sense. There is a clear and vehement answer to those people who are still worried about the way they build houses. The answer is “Go back to the Nature and recapture the green we are losing day by day.”
Listen, the mud earth will tell the story. Vasthukam-the organic architecture run by Mr. P K Sreenivasan is under the pursuit of bringing back the green earth. He had his greatest building experiences while working under the master craftsman and the chief architect of Cost Ford, Mr. Laurie Baker. That was the beginning of his journey seeking the answer how far a building can be cost-effective and eco friendly fulfilling the dreams of layman. He has experimented with various materials like country brick, laterite and mud. He was one of the main engineers who brought forward the exposed laterite buildings in the year 1992. But still he was concentrating on the importance of making a house more eco friendly and greener. Taking into consideration the fact that construction is the main resource intensive sector today the need for getting attuned to nature intensifies
How far is it possible? The unfriendly and anti eco materials used in the construction give the house a certain sense of aloofness from nature. A sensible analysis of this barrenness of new buildings forced the engineer return, to take a ride back to the traditional mud houses of  Kerala where antique glow held its head high. His frequent visits were followed by a detailed study on the traditional mud houses, their merits and demerits. Art always take its steps from nature to the infinite. Mr. Sreenivasan was lucky to build his first Mud guest house of 5300 sq.ft at Aadisakti a prestigious theatre campus based in Pondichery
Save the River
It was Sreenivasan who first introduced the technique of smooth plastering of the walls using mud. This technique helps to reduce the use of fifty percent of sand that is needed while plastering the walls. This technique also helps to avoid painting the walls and the unhealthy consequences of breathing toxins. Taking the long view, thepainted walls are blockages in the natural flow of life and wasteful needing recurrent yearly paintings. 
Here, the ethnic feeling of mud walls scores high. The organic feel of the smoothly plastered mud walls complete the smoothness of Grecian urns. A questionnaire survey conducted among the proud owners of mud houses repeatedly assures that they simply could not resist feeling the richness and smoothness of their walls. We may appreciate a decoratively painted wall from a distance without taking it into our hearts. The combination of chemical colors may make sense for a short time but in the long run it may be pushing us to tip toe into unsound respiratory problems. Needless to say, the unpolluted mud walls plastered with smoothened mud is ever hugging and its texture is tempting. Those who visit the mud houses designed by Sreenivasan are struck by the smoothness of the mud walls which can not be ignored.  
“The walls of different mud houses are in different shades” says the proud engineer. Deep red, soft yellow, yellow ochre, chrome yellow, muted brownish gold that may provide a perfect background for antique rose wood furniture or teak window frames. This is one of the main achievements he has found out while exploring the possibilities of mud. Using different types of mud, or mixing different textures of mud, a variety of natural colors could be made possible. The colors thus derived from the Mother Nature are capable of challenging the artificial color industry. These natural walls offer a flow of space and freshness of air
Nature within nature where all living beings, surroundings, its animate and inanimate forms blends into harmony is the dream of Vasthukam.
